Background

The main body of the liquid crystal display is made of liquid crystal materials, each liquid crystal material has fixed Ts (crystallization point) and TL (clearing point), and the liquid crystal display can normally display only under the temperature condition within a certain range of Ts-TL. At present, commercial or industrial liquid crystal displays produced by various large panel manufacturers often have the adverse phenomena of slow response speed, trailing dynamic pictures and the like in a low-temperature environment below zero centigrade; when the ambient temperature is lower than Ts of the liquid crystal display, even freezing of the liquid crystal material occurs, so that the liquid crystal display completely loses the function of normal display. Therefore, in a low temperature environment, a heating method is generally adopted to increase the liquid crystal temperature, so that the liquid crystal display can meet the requirement of normal use. The heating and temperature raising of the liquid crystal display are particularly important in the military field.

At present, a conventional liquid crystal display which is heated by using ITO conductive glass at a low temperature comprises a structural shell, a liquid crystal screen assembly, an optical backlight system, a circuit control module and the like. Wherein, a heating layer is arranged in the liquid crystal screen component, and the heating layer is usually made of ITO conductive glass. The sheet resistance of the ITO conductive glass is generally relatively uniform, and relatively uniform heat can be provided for the liquid crystal screen under a certain voltage condition. The defects caused by the heating mode are obvious, and the difference of heat dissipated to the periphery of the liquid crystal screen assembly through the metal shell and the window glass of the liquid crystal screen assembly is large, so that the surface of the liquid crystal screen of the liquid crystal display working in a low-temperature environment has large temperature difference. The liquid crystal display mainly shows that the central temperature of the liquid crystal screen is high, and the peripheral temperature is low, and the phenomenon that the edges, particularly four corners, are whitish or bluish can occur when the liquid crystal display displays a black field at low temperature due to the temperature difference. If the heating power consumption is increased, the display defect cannot be overcome, but the temperature difference on the surface of the liquid crystal screen is larger and larger, and the normal display effect of the liquid crystal display is seriously influenced.
